3D Mapping in Freemode

Once a calibration is done, you can align it using 3D model data and virtual camera positioning.

In order to perform 3D alignment, you will need:

• The initial calibration (completed) with blending. No VC adjustment and no warping.

• The 3D model of the screen with its UV map (refer to 3D Model Handling).

Workflow

1. Load the calibration in VIOSO and activate it, so you can see the calibration result on the projectors.

2. Make sure the warping Virtual Canvas (VC) is untouched and it is set by default to full screen.

3. Open the Player window. On the main menu, click the plus icon. Then choose Add Model Item then Add MRD – give it a name — this will create an MRD file in the playlist.

4. Double-click on it to activate it, so it is in “playing” status:

   
5. On the main window, un-check the Show test image checkbox, as this test pattern will always be shown on top of playlist content.

6. Click More... menu on the main window and choose 3D Mapping.
7. Align the virtual camera parameters to your real calibration camera measurements. Refer to the section 3D Mapping for details and examples.

8. The 3D alignment is now finished, you can proceed by performing the conversions: Step 4: Final conversions
